To develop a simple and accurate delirium prediction score that would allow identification of individuals with a high probability of postoperative delirium on the basis of preoperative and immediate postoperative data.Postoperative delirium, although transient, is associated with adverse outcomes after surgery. However, there has been no appropriate tool to predict postoperative delirium.This was a prospective observational single-center study, which consisted of the development of the DELirium Prediction based on Hospital Information (Delphi) score (n = 561) and its validation (n = 533). We collected potential risk factors for postoperative delirium, which were identified by conducting a comprehensive review of the literatures.Age, low physical activity, hearing impairment, heavy alcoholism, history of prior delirium, intensive care unit (ICU) admission, emergency surgery, open surgery, and increased preoperative C-reactive protein were identified as independent predictors of postoperative delirium. The Delphi score was generated using logistic regression coefficients. The maximum Delphi score was 15 and the optimal cut-off point identified with the Youden index was 6.5. Generated area under the (AUC) of the receiver operating characteristic (ROC) curve was 0.911 (95% CI: 0.88–0.94). In the validation study, the calculated AUC of the ROC curve based on the Delphi score was 0.938 (95% Cl: 0.91–0.97). We divided the validation cohort into the low-risk group (Delphi score 0–6) and high-risk group (7–15). Sensitivity of Delphi score was 80.8% and specificity 92.5%.Our proposed Delphi score could help health-care provider to predict the development of delirium and make possible targeted intervention to prevent delirium in high-risk surgery patients.

SISMAD represented variable angiographic changes, and its clinical course was benign in this study. For patients with SISMAD, if there is no evidence of bowel infarction, bleeding or aneurysmal changes, conservative treatment with close follow-up is sufficient and could reduce unnecessary endovascular interventions.

A total of 1,503 solid organs were procured from 449 deceased donors in 2018. Although the number of donors was down by 12.8% from the previous year (8.7 per million population), the number of organs procured per donor increased from 3.29 in 2017 to 3.35 in 2018. While the causes of brain death by cerebrovascular diseases and head trauma from traffic accidents have declined, brain damage from hypoxia has increased slightly. The most prominent change in the decline of organ donations was a decrease in family consent (36.5% in 2018 vs. 42.9% in 2017). The disagreement over organ donations by other family members even extended beyond the next of kin, and the restriction of organ donations in connection with the suspension of end-of-life care partly affected the consent rate, making this a controversial social issue. An accurate analysis regarding the factors causing the decline of familial consent rates is required, and related organizations along with the government should make a unified concerted effort to resolve this issue. To help achieve this goal, this manuscript describes the transplantation process and briefly explains the Korean domestic organ donation system.
